Not to be arrogant or anything, but my own analysis usually works better for me than those from professional analysts.

To give you an example, there were many financials (BSC, AIG, LEH, FNM, FRE, WB, MER, etc) that received predominantly buy or overweight ratings from professional analysts.

Then, after the share price halved, they were still rated buy, overweight or at least hold. Credit ratings? Same story. Downgrades come when most damage is done, not before the companies get in trouble.

My advice is to listen to no one but yourself. Professional analysts always have some kind of interest in attracting either buyers or sellers.
